Risk of breast cancer-related death in women with a prior cancer
Figure 4. Kaplan-Meier survival curves of patients with breast cancer as the second primary cancer or the prior cancer. (A) BCSS was significantly shorter in patients with breast cancer as the second primary cancer than in those with breast cancer as the prior cancer in the entire cohort. (B) OS was significantly shorter in patients with breast cancer as the second primary cancer than in those with breast cancer as the prior cancer in the entire cohort. After PSM, both BCSS (C) and OS (D) were significantly lower in patients with breast cancer as the second primary cancer than in those with breast cancer as the prior cancer.
